Hey, I never noticed that!
$ dmesg | grep APIC
Local APIC disabled by BIOS -- reenabling.
Found and enabled local APIC!
Using local APIC timer interrupts.
calibrating APIC timer ...
PCI: Disabling Via external APIC routing
Note, though, "Disabling Via external APIC routing" and this:
$ cat /proc/interrupts
CPU0
0: 563586560 XT-PIC timer
1: 3329762 XT-PIC keyboard
2: 0 XT-PIC cascade
3: 1461 XT-PIC usb-uhci, usb-uhci, ohci1394
4: 9363329 XT-PIC eth0
8: 522 XT-PIC rtc
10: 38402578 XT-PIC ide2
12: 18145483 XT-PIC PS/2 Mouse
14: 7005607 XT-PIC ide0
15: 1311 XT-PIC ide1
I'd have noticed a long time ago if there were more than 15 IRQs.
